Definitions

  • Fig. 1 shows the basic structure of an implantable defibrillation assembly 1, as shown in US 5,531,766 is known.
  • a defibrillator 3 In order to stimulate the heart H of a patient P, a defibrillator 3 is in electrical communication with an electrode lead 5 ', which here carries a special electrode ("shock electrode") 7, which is located at its distal end and is placed in the heart of the patient , The defibrillation is usually via a current path between this electrode and a counter electrode, which is more or less remote from the heart to be stimulated.
  • the housing 8 of the defibrillator 3, which contains the units for the detection of cardiac signals and generation of electrical pulses, can act as a counter electrode. Alternatively, a counterelectrode may be attached to the electrode lead or to the exterior of the housing.
  • the outer lead 9 leads the lead structure 10 to the ring electrode 4 and the inner lead 6 to the tip electrode 2.
  • the contact between the leads and the electrodes is either directly ( Fig. 2a ) or by a conductive connecting element ( Fig. 2b-c ), which is a matching mounting pin 11 or an electric cable 12.
  • the inner lead In a first configuration, the inner lead is moved by rotation and its end displaced from the end of the outer lead. Since both supply lines are in fixed position relation to one another at the proximal end, the outer supply line must be compressed here and / or the inner supply line must stretch.
  • the rotation and the displacement of the inner feed line are in this case transmitted by a transmission element to the first electrode.
  • the transmission element which has a low longitudinal stiffness, connects the inner lead to the first electrode, without making a galvanic contact, which only mechanical loads (forces and moments) To establish contact, whereby only mechanical loads (forces and moments) of the inner supply line are transmitted.
  • Fig. 6a and 6b show the distal end of a stimulation electrode lead 5 similar to FIG. 3a in which the transmission element has the shape of a hollow coil 13d, in which the connecting lines 14, 15 extend.
  • the pitch of the screw electrode 2 is equal to the pitch of the hollow coil 13d, in order to reduce the mechanical stress on the connecting lines 14, 15, when turning.
  • the hollow coil 13d here consists of conductive material, wherein the front part, which is in contact with the first electrode 2, is electrically insulated.
